nope, "None" here (when passed to `node.create_subdirectory(mutable_version=)` means the client's default mutable type. I fixed the receiving end to interpret it that way in a later patch.

but in general, yeah, the idea is to consolidate the notion of "what is the client's default mutable type" into just one place, in the NodeMaker. Not sure I quite hit that, but that's the goal.
